Featured Reviews

Ahmed Naguib - PeerSpot reviewer
Director at Techpace
Dashboard design excels while prediction algorithms need improvement
Splunk User Behavior Analytics is still an immature product, so it still needs some R&D to be able to be mature in the market. The prediction, algorithms, and ML codes behind Splunk User Behavior Analytics need to be more tuned. The logic needs to be reviewed because it has many false positives. For Splunk User Behavior Analytics, it is not yet a mature product and we are not recommending this to mature customers for now. The machine learning algorithm in Splunk User Behavior Analytics is actually the core thing that needs to be updated because this feeds all the other functions inside it. If the ML functions are not good enough, that means the risk scoring and all other related information will not be correct.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's straightforward in terms of configuration and troubleshooting and log management and monitoring as well. These are the edge points in addition to it being a modular solution where you can capitalize on your current licenses with extra licensing models, which can match the customer's business requirement and it can help the customer to design or to actually plan for their own roadmap."
"The solution is fast, flexible, and easy to use."
"Because of some of the visualizations that we utilize, we are able to understand strange, unusual traffic on our networks."
"The best features in Splunk User Behavior Analytics include anomaly detection, behavioral profiling, and risk scoring and prioritization functionality."
"Splunk User Behavior Analytics is known for its advanced analytics and data correlation capabilities, which help in detecting patterns, anomalies, and security threats."
"After more than three years of using this solution, I would recommend this solution, especially for environments that have a big volume of data."
"The most valuable feature is the ability to search through a large amount of data."
"It is a solution that helps test and measure customer satisfaction."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"I think they could have a built-in user behavior analytics engine, and more advanced artificial intelligence features as well."
"In terms of improvements, advanced reporting could see enhancements as there are some issues with latency. Additionally, there are challenges with configuration findings during lexical analysis."
"It would be good if the solution had an analytics tool that allowed us to analyze the data without writing specific queries."
"The correlation engine should have persistent and definable rules."
"The dashboard part could be improved."
"One thing I would say is that they should continue to expand it on more devices."
"We'd like the ability to do custom searches."
"Currently, a lot of network operations need improvement. We still need people to handle incidents. Our vision is to leverage status and convert it directly from the network devices. It would be ideal if we could take action using APIs and API code and remove manual processes."
"Support is an issue because they have a limited number of resources."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
 

Pricing and Cost Advice

"Pricing varies based on the packages you choose and the volume of your usage."
"I hope we can increase the free license to be more than 5 gig a day. This would help people who want to introduce a POC or a demo license for the solution."
"The licensing costs is around 10,000 dollars."
"There are additional costs associated with the integrator."
"I am not aware of the price, but it is expensive."
"My biggest complaint is the way they do pricing... You can never know the pricing for next year. Every single time you adjust to something new, the price goes up. It's impossible to truly budget for it. It goes up constantly."
"It’s a single license platform."
